Modes Of Operation - Miele DA 3668 Operating And Installation Instructions

Modes of operation

Depending on the model of the cooker
hood, the following options are
available:
Extraction mode
The air is drawn in and cleaned by the
grease filters and directed outside.
Non-return flap
The non-return flap is designed to
prevent the exchange of room and
outside air taking place when the
cooker hood is switched off.
The flap is closed when the cooker
hood is switched off.
When the cooker hood is switched on,
the non-return flap opens for the
cooking vapours to be blown directly
outside.
If the on-site ventilation system does
not have a non-return flap, the non-
return flap supplied must be fitted in the
exhaust socket in the motor unit.

Recirculation mode
Recirculation mode cooker hoods
require a conversion kit and charcoal
filters (see "Technical Data")
The air is drawn in and cleaned first by
the grease filters and then by the
charcoal filters. The cleaned air is then
recirculated back into the kitchen.
